Hi,
If I understand right, u have created an entity bean with id=0. Lets say the bean has
two members id = 0 AND name = 'John Matthew'.
Once u fire a create, this creates a database record. However, coz of the trigger the
record is updated with id = some value, say id = 3. Now there's no record in the
database with id=0. Now if u fire a findbyprimarykey with id = 0, there's no record
matching that value!!
Now if u try to invoke a method on the same bean reference, u wud get the
ObjectNotFoundException coz, the container will try to activate it (in short fire a
query on the table with the where clause something like id = 0 which won't return any
records!!).
I suggest, define a method on the bean to retreive the value that was updated by the
trigger and use that value to fire a findbyprimarykey.
Best Regards,
dev

Subject:[EJB-Developer] Problem in ejbcreate and ejbPostcreate
hi
I developed some entity beans .
in which one field is a primary key , but in database
it is an auto increment field .
SO, what i did i wrote a trigger which update my id after each insert .
But in ejbpost create , after crating an entity bean with the id=0 ,
Getting new id from database and assinging the new id to the entiy bean (CMP)
when i try to find out the bean with primary key(0) (by findByPrimaryKey())
i am getting the exception ObjectNotFoundException.
Before assining the new primary Key (id)
how the primary key(id) is changing ??
Thanks
